Abstract

A test and measurement device of force, electricity and magnetism couple is featured as using the stepping motor to drive transition component to rotate so as to make devices on transition rod move vertically under action of two spacing blocks for realizing axial tensility and compression of sample and recording load value by load transducer; utilizing DC constant voltage to provide electrical field, using standard four lead wires to measure value of current and voltage; providing external magnetic field by super conductive magnet container.

Description

technical field [0001] The invention relates to a test and measurement device for force, electricity and magnetic coupling, belonging to the technical field of measurement. Background technique [0002] The development of new materials is one of the cornerstones supporting the progress of modern science and technology. With the continuous expansion of the field of human activities, the use environment of many materials is extremely complex, and it is often necessary to meet multiple performance requirements at the same time. For example, the mechanical and electrical properties of piezoelectric materials should be considered at the same time during use, and superconducting magnets often have to bear the simultaneous action of mechanical load, electric field and magnetic field during use. [0003] Studies have found that many materials often exhibit complex properties under the simultaneous action of the above-mentioned different types of loads (mechanical, electrical, magne...
